Lion's Paw Shells are known to be associated with courage and strength, abundance and prosperity.
When I see these, I also can't help but to think of mermaids and water magic!
They have been used in so many ways including offering plates/bowls on altar spaces. Add herbs, a candle, some tumbled stones or maybe some mini spheres.
I've seen them used as soap dishes or on their own as beautiful decor and honor to the water element.
